Considering a wireless social network, we investigate a cooperative jamming scheme based on the space power synthesis with unknown channel state information (CSI) of eavesdroppers. In particular, we provide a multiple jammers-based anti-eavesdropping model and formulate it by a superposition principle of various jamming signals in a free space. Based on the model, we analyze the superimposed effects...
A Mobile Social Network (MSN) is a typical Delay Tolerant Network (DTN) composed of mobile nodes with social characteristics. Routing design and optimization are difficult because of the fast topology changes in such network. However, realistic mobility trace shows that mobile nodes in MSNs generally visit a few locations called homes, frequently, while other locations are visited less frequently...
Due to the increasing number of wireless mobile devices, the possibility of mobile communications without infrastructure becomes a reality. The Decentralized Mobile Social Network (DMSN) is a paradigm where nodes can move freely and organize themselves arbitrarily. Routing in these environments is difficult for the reason of the rapid changes of the social relationship graph's topology. Meanwhile,...
With the increasing number of wireless mobile devices, the possibility of mobile communications without network infrastructure is becoming a reality. The decentralized mobile social network (MSN) is a paradigm where nodes can move freely and organize themselves arbitrarily. Therefore, the key challenge is to find routes that can provide satisfactory delivery performance and low average end-to-end...
